## Summary by CodeRabbit

- **New Features**
  - Added a method to cycle through shape types when using the shape tool.

- **Bug Fixes**
  - Improved shape tool behavior to ensure the selected shape type does not change unexpectedly after adding a new shape.

- **Tests**
  - Added an end-to-end test to verify that the shape tool retains the selected shape type after adding a new shape.
  - Enhanced shortcut tests to verify cycling shapes forward and backward using 's' and 'Shift+s' keys.

- **Refactor**
  - Streamlined the logic for cycling through shape types and connector modes for improved maintainability.
  - Removed external utility for cycling shapes, integrating the functionality directly into the shape tool.
  - Updated keyboard shortcut handling to use the new cycling method within the shape tool.
